Abstract
A high-speed and high-power modified uni-traveling-carrier photodiode (MUTC-PD) is optimized and fabricated. The optimization method takes carrier transport as the core and considers the hole transport time limited bandwidth of the MUTC-PD for the first time. Taking into account the impact of the electron transport time and RC time constant on device performance, the device is simulated and fabricated. In structure epitaxy, it is proposed to use graded doping to fit Gaussian doping to reduce the epitaxial growth error. The measured bandwidth of the MUTC-PD reaches 34 GHz and the RF output power reaches 17.1 dBm with the mesa diameter of
$20~\mu \text{m}$
. In addition, the influence of modulation depth on high-speed and high-power performance is studied.
期刊介绍：
The IEEE Journal of Quantum Electronics is dedicated to the publication of manuscripts reporting novel experimental or theoretical results in the broad field of the science and technology of quantum electronics. The Journal comprises original contributions, both regular papers and letters, describing significant advances in the understanding of quantum electronics phenomena or the demonstration of new devices, systems, or applications. Manuscripts reporting new developments in systems and applications must emphasize quantum electronics principles or devices. The scope of JQE encompasses the generation, propagation, detection, and application of coherent electromagnetic radiation having wavelengths below one millimeter (i.e., in the submillimeter, infrared, visible, ultraviolet, etc., regions). Whether the focus of a manuscript is a quantum-electronic device or phenomenon, the critical factor in the editorial review of a manuscript is the potential impact of the results presented on continuing research in the field or on advancing the technological base of quantum electronics.
